of the car, and has for its object to rovide implroved means for holding the carody in its orizontal or o erative position while the car is being loade .or while it is in motion in transporting the load, so that provision ma be made for the automatic adaptation of suc means to movement of the parts when the car is rounding short curves. One form of device for this purpose is illustrated and described in my pendlng application, Serial No. 393,501, filed September 18, 1907. I aocomplish this ob ect as illustrated in the drawings and as hereinafter described,

What I regard as new is set forth in the claims.

In the drawings,Figure '1 is a partial side elevation of a dumpcar, illustrating my 1mprovements; Fig. 2 is a detail, showing certain of the parts in edge view; and Fig. 3 is a sectional view on line 3-3 of Fig. 2.

Referrin to the drawings,4 indicates the car-bo( y platform and 5 one of the side gates.

6 indicates one of the trucks,in cars of this type there being usually two trucks, one near each end of the car-ho 78 indicate upper and lower members, which together pivotall. support the carbody so t or other equivalent device, being preferably provided at intervals throughout the lengt of the car, in the usual way.

9 indicates a chain for'holding the carbody in its normal osition so as to revent tilting thereof when oading or when t e load Specification of Letters Patent.

dinally of the car by means of a swiveled yoke or coupling 11 which engages a swingin link 12. Said couplin is provided with a r0 ler 13 whichb'ears a must the under side of the upper portion 0 the link 12, as best shown in Figs. 2 and 3, said link having a longitudinally-extending portion 14 at its upper end of suitable shape to bear upon said rol er to form a way alon which the roller may travel as the car-body and truck shift, with relation to each other in 'roundin curves. The .link 12 is pivotally connecte by a pivot 15 with the .truck, as shown-in most position when in use, as shown in ig. 2, at which time it bears against the upper portion of the truck or other stop conveniently arra ed;

As est shown in Fig. 1, the chain 9 is provided with a hook 16, the end of which is secured by a ring 17 in the usual way so that the chain is separable intermediately to release the car body and permit it to be dum ed. By using a swiveled connection for t e chain, as described, twisting strains are avoided, so that by this means in connection with the capacity for 10 itudinal movement secured by em 10 t e longitudinal g t e stay chains ma readily accommodate themselves to the various strains to which the parts are subjected in rounding curves. The length of the chain may be adjusted by ad'usting the bolt portion 18 of the swivel. It will be understood that instead of a chain anv other flexible connection may be employed. a

Thatwhich I claim as m invention, and desire to secure by Letters atent, is,-

.1. In a dump-car, the combination of a laterally-tilting car-body, a truck, a stav chain connected at its upper end with the car-body and at its lower end with the truck, the lower end of said chain being movable longitudinally of the car.

2. In a dumpcar, the combination of a. laterally-tilting car-body, a truck, a stay chain connected at its upper end with the car-body and having a swiveled connection at its lower end with the truck, the lower end of said chain being movable longitudinally of the car.

3. In a dump-car, the combination of a car-body, a truck, a chain connected at its i'i ected with the truck so as to move longituupper end with the car-body, and a; link pivotelly connected with the truck, the lower end of said chain engaging said link and being movable thereon longitudinally of the car.

4. In a dump-car, the combination of a car-body, a truck, a chain connected at its upYer end with the car-body, and a. vertical *-swinging link pivotally connected with the truck, the lower end of said chain engaging said link and being movable thereon 10 longitudinally of the car.
